Vincent Willem van Gogh was a Dutch Post-Impressionist painter whose work had a far-reaching influence on 20th-century art. In just over a decade he produced over 2100 artworks, including around 860 oil paintings, the majority created in the last two years of his life. They include portraits, self-portraits, landscapes, still lifes, olive trees, cypresses, wheat fields and sunflowers, and are characterised by symbolic colourisation and dramatic, impulsive and highly expressive paintwork. He sold only one painting during his lifetime and was largely unnoticed by critics until his suicide, aged 37, which followed years of restless anxiety, poverty and mental illness.
